The book's premise is centered around Adlerian theory, a decades-old psychology coined by Alfred Alder, an Austrian psychotherapist.
At the heart of the book, and Adlerian theory, is the idea that "freedom is being disliked by other people."
The authors emphasize that when you follow where life is leading you, not everyone will be on board with what you're doing.
While you shouldn't go out of your way to be disliked, you should avoid being afraid of being disliked because it is inevitable.
This leads into one of the biggest lessons that the book touches on, which is that "happiness is a feeling of contribution."
